ASoC: hdac_hdmi: Remove 'edev' NULL check
Commit 4a3478debf36 ("ASoC: hdac_hdmi: Add jack reporting")
leads to the following Smatch complaint:
sound/soc/codecs/hdac_hdmi.c:971 hdac_hdmi_present_sense()
warn: variable dereferenced before check 'edev' (see line 967)
As explained by Subhransu S. Prusty:
"This NULL check is not required, can be removed.
edev object is expected to be present when the present_sense is
called. This is called from places where this edev object is
already available."
So remove the evdev NULL check.
